Stickley Dining Set

I have a Stickley dining table with 6 chairs. It has two attached leaves that swing out with a hinge mechanism. They are not removable. My family has had it as long as I've been alive, which puts it a minimum of pre-80s, though I believe it was bought used so it could be any age. It seems to be in the colonial style. The chairs have been covered, but they are cained. I can't find much about it. Any help?
